v0.6.0 · GitHub support and sprint planning

Added

• GitHub App support: connection setup, install callbacks, webhook ingest, synced external resource mappings, issue-detail GitHub links, and MCP tooling/docs for linked GitHub work.
• Sprint management workflows: edit, rollover, guarded create, backlog planning, and delete flows with audit-backed issue movement.

Changed

• Roadmap is now a working timeline with initiative, date coverage, and progress filters, visible sprint bands, no-date rows, and inline project date editing.
• Issue creation now shares one service path across UI, API, and MCP.

Fixed

• Sprint and project date guards are enforced server-side through tRPC and MCP.
• Side-panel interactions no longer leak to Mission Control shortcuts.

Verification

• Released from 4935ec8 and deployed live on 2026-06-09.
• Passed prisma generate, typecheck, lint, docs build, full Vitest, full Playwright e2e, and live smoke checks.
